[Plugin] Solids Penetration Check

voljanko

I would also like to change the colour of the result to make it more visible,but I don't know how.
Any suggestions?

Create a material and apply it to the entities.

` my_material = model.materials.add( 'IntersectionMaterial' )
my_material.color = 'orange'

face.material = my_material
group.material = my_material`

Trying to read your code - but I struggle to follow the code flow. Seems that your indentation isn't properly aligned throughout your code...

voljanko

Updated version:
-now is a tool (you can zoom to check the penetration area)
-automatic x_ray view
-red colored penetration area
-new name

Now seems very cool

voljanko, I see this is how you did it in your plugin. But the way you have it set up, you add a new identical material every single time your plugin is run. You can open up "Window > Model Info > Statistics" to check the number of materials.

You don't need to define a new material. Instead use the following, which will only ever add one pre-defined material to your drawing, no matter how many times you use it:
group.material = 'red'

Ok,thanks.
Updated.
Please note,if you have a big model (more than 20 solids),the plugin will need more time to compute all the intersections.
If you want to see that plugin is doing something (not freezed),you can select the Outliner (Window menu) as the activity display.It can be some kind of progress bar.

Please help me find the solution for this bug:
-when one solid is a subcomponent and a subgroup in a component, the plugin can't find the penetration.
I know the problem is in line 132 def1=solid1.entities.parent ,but don't know what to do about it.
Thanks

You probably have more experience playing with components, than me. But what I can see is, there is no need to blame sub(groups or components), yet. Your plugin doesn't even work for two simple intersecting components. "def1=solid1.entities.parent" finds the definition of groups, not components. Component instances don't have the method for "entities". It's the component definition that has that method. That's why the error message saids undefine method. It should be something like "def1 = componentInstance.definition" for components.

Also, another strange thing(bug?) I see is when you have (group or component) inside a (group or component), I get a volume of "-1.0"

voljanko

Ups,I was sure that tested with components.Now it is ok and updated for download.
Now the code indentation is properly aligned so perhaps readable

You wrote :"Also, another strange thing(bug?) I see is when you have (group or component) inside a (group or component), I get a volume of "-1.0"

Sketchup assign the volume to -1 when the item is not a solid.If you mean something related to my plugin,please explain more.

You wrote:"That's why the error message saids undefined method."

How do you get this message?Hod do you debug? Im only using message boxes to debug.

No, I just mention it just in case you didn't know about it. Components are hard for me to follow, so I just briefly looked through your code to learn more. At 1st, I was thinking this was causing your bug. But then figured out the error message.

Error messages are printed out in the Ruby Console. See picture of one way I debug, by running small snippets of code with Jim Foltz's "Web Console" plugin. Jim also has a "Ruby Toolbar" plugin, that lets you reload your plugin. But I think you need to add a check for if the plugin has been installed previously, or you will get multiple menu items.

require 'sketchup.rb'

if( not file_loaded?('solids_penetration_check.rb') )
	plugins_menu = UI.menu("Tools")
	plugins_menu.add_item("Solids Penetration Check") { penetrationcheck }
end
file_loaded 'solids_penetration_check.rb'

Thank you thomthom for your suggestions.
I have test the plugin on a model with 31 solids organised in many subgroups and it takes 40 seconds to
find 10 "penetrations".So it is slow and need some speed-up like you suggest.

Any way to get this to Intersect With Model to make bright orange(selectable color) lines to check all the other geometry that is NOT solids?

Richard

voljanko

Yes,there is a way,why are you asking
Anyway,if you want to find the mistakes,that makes your group a non-solid,there is another plugin - Solid Inspector from thomthom.

glro

is the plugin able to check intersections between solids when they are part of components?
i checked, and it doesn't seem so

the connections are solids, intersection is detected when they are outside the component, and not when theyare inside

is there a way to solve the problem?

bracing connection intersection

I don't draw with solids. Need a tool to check all the other things I draw to look for possible overlap conflicts between components, groups etc. 'Tile components' "intersecting" 'cabinet components' for instance...

EDIT:SOLVED

i cannot help you concerning the ruby programming, but i tried your plugin on the model included in your post, and it worked perfectly; event when i made a component from the component and the group

i tried it also on the file included; components with solids inside, it worked, but in a strange way; i would like to know which are the components that interfere, but the information vanishes when the program stops...

where are the components that intersect?

penetration detected

Aaaar it does not work with free versions... Can you do something?
